in California, at least SoCal, this "rule" has no meaning, as the congestion is at maximum level. there are simply too many cars for fast traffic to even be possible. even during non-rush hour periods the congestion is ridiculous. the only time I've driven comfortably on the highway is after 11pm and before 6am.
